An 82-year-old Rapid City resident and his son are trying to create a memorial to remember the crash of a B-17 bomber on the edge of the city 70 years ago.

Harold Stone tells KNBN television that he was 12 years old when he ran to the crash site on Sept. 6, 1943.

Witnesses say the plane from the Rapid City Army Air Base was flying nearly straight down when it hit the ground. All 10 people on board were killed.

Stone and his son, Greg, have used old photographs and key landmarks to relocate the crash site. They are hoping to secure funding for a permanent monument to remind people of what happened and honor those who lost their lives.
